Quick question, when you deposit the 800,000 into a Thai bank account do you have to prove it came from overseas like the monthly method or not

TLDR : Answer Summary
The requirement to prove that the 800,000 Baht deposited into a Thai bank account came from overseas varies by immigration office. When applying for a Non-O Visa, some offices may require proof of an international transfer for the initial application, while this is generally not necessary for the subsequent 1-year extension of stay.

800,000 for what?

If trying to convert from tourist to non-O visa inside of Thailand, a common requirement is to be shown that it's an international transfer.

If trying to apply for the 1-year extension, it's not a common requirement to show that.

Some Immigration Offices require that for the initial Non-O Visa but it is not a requirement for the 12 month Extension of Stay.

That’s going to be office dependent. Some require it to be shown as an international transfer, some just want the balance.
